Everything mnml.ai does — and the parts it doesn't.

✎

Sketch to Render

Hand sketches, napkin drawings, or CAD linework to photoreal with true-to-line geometry lock.

▣

Interior AI

Restyle rooms, furnish empty spaces, swap materials from a real product library with links to suppliers.

◫

Floor Plan → 3D

Turn 2D plans into furnished 3D views and walkthroughs. Room labels and dimensions read automatically.

▶

Video Walkthroughs

Generate 4K cinematic fly-throughs and day-to-night timelapses from a single render.

◎

Region Edit & Inpaint

Brush any area — change the façade cladding, add people, replace the sky — without re-rendering everything.

⧉

Native Plugins

SketchUp, Revit, Rhino, Archicad and Blender plugins. Render straight from your viewport.

◐

Local Context

Climate- and region-aware materials — from East African laterite to Dutch brick — for believable site renders.

⌗

Quantity Insight

Rough material take-offs (blocks, cement, tiles, roofing) estimated from your render to speed early costing.

⚑

Team Workspace

Shared boards, client review links, comments, version history and brand style presets.

Superpower automations

One upload. A whole client pack.

Run multi-step pipelines in the background: Plan → isometric 3D + finished exterior + priced BOQ. Sketch → day, night, aerial and interior renders with a written presentation brief. Style Explorer → four variations at once.

◫

Floor plan → full structure

2D plan becomes a furnished 3D cutaway, photoreal finished building, room schedule and structural system.

⌗

Priced bill of quantities

Blocks, cement, sand, steel, roofing and tiles priced for Uganda, Kenya, NL, UK, UAE or USA. CSV export.

◉

Reference prototypes

Upload up to 4 reference images. Serene borrows their materials, palette and mood while keeping your geometry.

▶

Video walkthroughs

Walkthroughs, drone flyovers, orbits and day-to-night timelapses with ambient sound, from any render.

▤

Accounts & saved projects

Every render, video and estimate saved permanently to your projects.

✦

Brief → concept

Paste a client brief, get a named concept, programme, materials, sustainability strategy and hero render.
